. Specification of Letters Patent.

Patented Feb. 13, 1906.

Application filed September 7, 1905. Serial No. 277,462.

To all whom, it Tnay concern:

Be it known that I, LoUIs HAENLEIN, a citizen of the United States,residing in East Rutherford, in the county of Bergen and State of NewJersey, have invented certain new and useful Improvements in Bronzing-Machines, of which the following is a specification.

This invention relates to certain improvements in bronzing-machines, andmore especially to an improved mechanism for operating the supply-rollerof the bronze-fountain so that it is rotated for a greater or lessertime, according to the size of the sheet to be bronzed; and for thispurpose the invention consists of a bronzing-machine comprising a doublecam rotated by the shaft of the sheetcarrying cylinder, a fulcrumedlever provided. in its lower curved part with an arc-shaped slot andcarrying a roller adjustable in said slot and moving in contact with thedouble cam, the opposite end of the lever being also slotted, anoscillating lever on the shaft of the fountain provided with a slot inthe lower end, means for connecting the slotted upper end of thefulcrumed lever and the slotted lower end of the oscillating lever, anda pawland-ratchet mechanism operated in connection with the upper end ofthe oscillating lever and adapted to impart the required motion to thesupply-roller of the bronze-fountain.

The invention consists, further, of certain details of construction andcombinations of parts, which will be fully described hereinafter andfinally pointed out in the claims.

In the accompanying drawings, Figure 1 represents in side elevation abronzing-machine with my improved motion transmitting mechanism for thesupply-roller of the bronze-fountain. Fig. 2 is a detail side elevationof the improved mechanism for operating the supply-roller of thebronze-fountain drawn on a larger scale, and Fig. 3 is an end elevationof the motiontransmitting mechanism.

Similar letters of reference indicate corresponding parts in thedifferent figures of the drawings.

Referring to the drawings, C represents the casing of abronzing-machine; F, a bronzefountain, which is supported at the upperpart of the casing in line with the stationary table T for the ingoingsheet which is to be bronzed; f, a supply-roller, which is rotated inthe bronze-fountain F and which serves to transmit the required quantityof bronze to the sheet that is fed through below the supply-roller ofthe fountain S, the shaft of the supply-roller, which is provided at oneend with a ratchet-wheelf, that is engaged by a pawlf pivoted to theupper end of an oscillating lever d. A lever d is applied to the shaftof the supply-roller and provided with a slot at its lower end, which isconnected. bya pivot d withthe upper slotted arm 6 of anintermediately-fulcrumed lever E, the lower arm 6 of which is curved,slotted, and graduated and provided with an antifriction-roller 6 whichis capable of adjustment by means of a thumb-nut if applied to thestud-shaft of the roller. The roller 6 projects somewhat beyond theinner edge of the lower arm 6 of the fulcrumed lever E, so as to formcontact with the circumference of a double cam D, which is rotated by agear-wheel transmission 9 g, as indicated in dotted lines in Fig. 2,from the shaft of the sheet-carrying cylinder O, the gear-wheel upon thecam-shaft being twice the size of the gear-wheel on the cylinder-shaft,so that the cam D makes one rotation for every two rotations of thecylinder O and imparts an oscillating movement to the fulcrumed lever Efor every rotation of the cylinder. A spring as is attached to thecasing of the machine and wound about the pivot of the lever E, so as toabut against the arm 6 of said lever, and thereby maintain the roller cin permanent engagement with the cam D. The lower slotted arm e of thefulcrumed lever E is curved so as to correspond to the curvature of thecam D, the outer edge of the lower curved arm 6 being graduated, so thatwhen the shaft of the roller is set in the slot along the graduations agreater or claim as new and desire to secure by Letters Patent 1. In abronzing-machine, the combination, with the shaft of the sheet-carryingcylinder, of a double cam rotated by the same, a fulcrumed leverprovided with a curved slotted and graduated arm, an adjustableantifriction-roller on said arm, means for permanently maintaining saidroller against said cam, an oscillating lever mounted on the shaft ofthe supply-roller, means for connecting the oscillating lever with theupper arm of the fulcrumed lever, and a aWl and-ratchet mechanismoperated by t e oscillating lever for transmitting the proper motion tothe supply-roller.

2. In a bronzing-machine, the combination, with the shaft of thesheet-carrying cylinder, of a double cam rotated by the same, afulcrumed lever adjacent to said cam and provided with a lower curvedslotted and graduated arm, an antifriction-roller adjustable in the slotof the curved lower arm, means for maintaining said antifriction-rollerin permanent engagement with said cam, a su ply-roller for thebronze-fountain, an oscil ating lever placed on the shaft of saidsupply-fountain, means for connecting the lower end of the oscillatinglever with the upper end of the fulcrumed lever, and apawl-andratchet-wheel mechanism between the oscillating lever and theshaft of the supply-roller.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

LOUIS HAENLEIN.
